Practicing Fantaisie Impromptu

[countrymath]

I started Fantaisie Impromptu 2 weeks ago following Benhard's and Chang's tips. I taked the most difficult bars, analized it and pasted it in a different sheet. On the first week, i managed to learn all this dificult bars, but they are not "mastered". They aren't even sounding good, but i can play all notes without stoping (besides the 2 bars after the arpeggio. They look easy, but i always miss a lot of notes). I think that if a keep practicing the same wasy i'm doing now, I will not make too much progress on the next week.

Can someone give me tips to "clean" this chunks out?

Here are the sheets i made:

Your first problem is that the score is upside down.  No wonder you're having difficulties.

If you are missing a lot of notes when you play then you need to slow down.  Practice the sections at less than half speed until mastered.

I don't really have any specific tips, just a few comments/ thoughts.
If you are missing notes, you might be playing too fast. =) 
What I do for difficult passages is to take a deep breath, focus, and then practise very slowly at a tempo where I can play the correct notes without stopping. Sometimes it's painful to practise slowly, at least for me, because a) I have to really focus and think about all the notes b) I know what it sounds like full speed and it sounds totally different slowed down... c) its harder to maintain a steady pulse. But its worth it, because eventually your hands get comfortable playing the tough parts and eventually they won't be a problem....

Also, progress isn't "linear", as in you might not be progressing much now, but who knows how much better you'll get next week? Every bit of serious practising helps

No wonder it doesn't sound good. You are playing it "upside down"

On a serious note, play it in a tempo that you master. Speed it successively and slowly up. Be patient and don't take too many steps at once. You will eventually gain success. I also think it is important to keep your fingers arched in this piece, at least in the fast parts.

Good luck!
